According to The Sun, Olivia Jackson crashed into a metal camera arm while shooting a high-speed motorbike chase in Johannesburg, South Africa.

She is currently in an induced coma with a punctured lung and head injuries.

"It wasn’t a very dangerous stunt," a source told The Sun. "She was riding a motorbike in a straight line but due to the scene she had no protective gear or helmet. There is a metal arm, which carries the camera along. But it malfunctioned and didn't lift up. It was totally out of her control. She had no chance. She is a lovely lady, the most generous person you could ever meet.”

Jackson has worked as a stunt double for many actresses in high profile films in recent years.

In addition to performing stunts for Daisy Ridley in Star Wars Episode VII: The Force Awakens, she also doubled for Karen Gillan in Guardians of the Galaxy and Charlize Theron and Rosie Huntington-Whitely in Mad Max: Fury Road.

In a statement on his Facebook page, Jackson's husband, David Grant -- also a stuntman -- wrote, "I want you all to know that she has been making steady progress and your thoughts and good vibes are all working so please keep them up! She's my inspiration and my world and one tuff little mother f—er ! She’s fighting hard … "

Grant was filming in Malta when the accident occurred and rushed to be with his wife in Johannesburg. The crash is currently under investigation.
